Andrade will be the toughest guy Bute has ever faced. Bute will need everything that he has to beat Andrade. Anything less, Andrade wins.
I give Andrade a 50% chance based on the Bika and Berrio fights. Bute has talent, but seems to struggle with aggression. Though he does appear to have a rock solid chin. I'm not sure if either man is capable of stopping the other with head shots, but it's going to be interesting to see how they take each other's body punches.
I agree Bute wins handily on UD, but you gotta admit you love seeing Andrade eat punches and keep coming.
